But as I noted in the comments in that method, some collections that should contain the columns (names, old values and new values) are always empty. And the Row Updated method is never even touched!!! NET Forums that I need to use a Data Source control.
All samples of course assume you’re doing everything in your page, but I have to do everything in my code-behind, because on forehand I don’t know what I’ll be binding to my Grid View.
But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.
When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.
This will lead to problems like "Grid View does not show updated values", "Grid View looses values changed by user". In your Page_load, this is typically only inside a block where you check to make sure that Page_Load is not being called during a post-back call.
For a while now I’m trying to figure out why my method, triggered by the Grid View.
In the Page_Load event, you simply load your data from the database and bind it with the Grid View control as shown below: For brevity I am not storing connection string in the web.config and also not using any Data Access Component.
